  • the present invention relates to managing data transfer between different types of tape media. More specifically, the present invention relates to back-up tape media migration and consolidation between heterogeneous tape formats.
  • Tape drives and media for backing-up data are enhanced over time with newer tape drives and media providing various benefits over older ones. As newer tape drives and media become more mature and gain market share, older tape drives and media are often phased out and become unavailable. For example, the sole remaining supplier of the so-called 36-tracktape drive recently announced that such drives will no longer be manufactured and that support is being discontinued. [0006] Tape drives such as the 36-track tape are typically supported for as long as the spare parts supply lasts. After that, users of obsolete tape drives having data stored on tapes associated with an obsolete tape drive have no way of accessing that data.

However, this data may become inaccessible where the old tape drive 104 fails and the necessary parts for repairing the old tape drive are not available.

Abstract

L'invention concerne un procédé et un système de gestion du transfert de données d'une bande d'enregistrement à une autre. Le système comprend un système d'exploitation de commande d'une pluralité de dérouleurs de bande et d'un gestionnaire de bande. Le système est configuré de manière à permettre à un utilisateur de créer une bande empilée, de désempiler une bande préalablement empilée, et/ou de consolider une bande préalablement empilée. Lorsqu'une pile est créée, des données sont copiées à partir d'une ou de plusieurs bandes d'entrée dans une bande de sortie sous n'importe quel format désiré selon les normes d'étiquetage standard de l'ANSI (American National Standards Institute). Lorsqu'un utilisateur désire désempiler des données, des volumes de bande virtuels (VTVs) d'une ou de plusieurs bandes d'entrée sont copiés sur une seule bande de sortie. Lorsque la consolidation des données ou la création d'une pile sont terminées, un répertoire est créé dans la bande de sortie.
